Chemical Name: Magnesium carbonate
Molecular Formula: x MgCO3 · y Mg(OH)2 · n H2O
CAS: 39409-82-0
Character: In normal temperature, it's with three hydrates. Light one is white, easily fragile or loose white powder. Odorless. Relative density is 2.2. Melting point is 350 ºC. It's stable in the air. When heated to 700 ºC, it will become magnesium oxide. It's hardly soluble in water, but it'll bring a slight alkaline reaction. It cannot be soluble in ethanol but could be soluble in olefine acid with sparkling.
Usage: It's used as a drier, color fixatives, anticaking agent, carrier, swelling agent, acidity regulator.
Packing: It is packed with a polythene bag as the inner layer, and a compound plastic woven bag as the outer layer. The net weight of each bag is 25kg.
Storage and Transport: It should be stored in a dark, dry, and ventilative warehouse, kept away from water and moisture; unloaded with care to avoid damage. Furthermore, it must be stored separately from poisonous substances.
